nusiiiasn-cumrnnkmrn ADJUSTMENT;

Application filed A ril 7,

1 0 all whom it may concern Be it known that I, EDWARD S. CHAnLEs, a.citizen of the United States, residing at Berwyn, in the county of Cookand State of Illinois, have invented certain new and use fulImprovements in Ensilage-Cutter-Knife Adjustments, of which thefollowingis a full, clear, and exact specification.

My invention relates to an ensilage cutter and more particularly to themanner of mounting and adjusting the knives on the flywheel.

The object of my invention is to provide an improved adjustable knifemounting for the flywheel of an ensilage cutter.

A further object is to provide a simple and inexpensive device whereby adelicate adjustment of the knife may be had without entirely removingthe bolts from the knife blade.

These and other objects are obtained by providing two oppositelydisposed beveled members having in-adjustable connection therebetween toeffect an adjustment of the knife.

In the drawings, Fig. 1, is a plan V ew showing the manner in which theknives are mounted on the flywheel.

Fig. 2 is an enlarged elevational view of my adjustable mounting.

Fig. 3 is a cross sectional view of Flgure 2, and

Fig. 4 is an enlarged plan view of the adjustable beveled member.

Like numerals of reference refer to like parts throughout the severalviews.

In carrying out my invention I employ the usual circular flywheel 10only a portion of which is shown, provided with the usual fan blades 11and having mounted at regular intervals a series of tangentiallyarranged cutting blades 12. These blades 12 are provided with forgedcountersunk bolt head portions 13 adapted to be secured in the seat 14of a beveled member 15. The member 15 is provided with an aperture 17extending vertically therethrough and registering with the aperture inthe countersunk portion 13 of the blade 12 for receiving a securing bolt18 for fixing the blade 12 to the flywheel 10. Additional means forfirmly securing the blade 12 to the flywheel includes a forwardlyextending car 19 formed integrally on the front portion of the member15. This 1921. Serial No. 459,263.

ear 19 is adapted to receiving a second securing bolt 20. i Q

'My improved adjusting mechanism includes an adjustable wedge member 21disposed between the flywheel 10 and the member 15. The wedge member 21is provided with an inclinedface 22 adapted to slidably engage theinclined face 16 of the member 15. The member 21 is made up of anencircling wall 21 having oppositely disposed ribs 23 at the basethereof and extending inwardly to engage the bolt 20 for preventinglateral displacement of the wedge member. The adjustable connectionbetween the wedge member 21 and the member 15 comprises an L-shaped bolt24, having one end 25' threaded and extending through an aperture '25 inthe wedge member 21 and the. other end 26 of said bolt extending throughan aperture 27 which is formed in the rearwardly extending portion 28 ofthe member 15. The bolt 24L is secured to the member 15 by a cotter 29.The threaded portion 25 of the bolt 24 is provided with adjusting nut 30and lock nut 31. 1

In the operation of adjusting the knife 12 upon the flywheel 10, thesecuring bolts 18 and 20 are loosened and the nuts 30 and 31 areadjusted in a manner to slide the wedge member 21 forwardly o-rrearwardly with respect to the member 15 and flywheel 10. In thisconnection it will be noted that the tightening or turning of the nuts30 and 31 in a clockwise direction forces the wedge member 21 forwardlyin a manner to position the blade 12 further away from the flywheel 10.When the propel-adjustment is attained the securing bolts 18 and 20 aretightened to firmly fix the blades in the adjusted position. From theabove description it is readily seen that a simple and eflicientadjustable knife mounting is provided and one in which it is unnecessaryto remove the securing bolts to effect an adjustment of the knifeblades.

While I have described but one embodiment which my invention may assume,it is to be understood that the same may be modified without departingfrom the spirit and scope of the appended claims. I WVhat I claim anddesire to secure by Letters Patent is: j

1. In an ensilage cutter, a flywheel, a knife support mounted on saidflywheel comprising a plurality of members, and means comprising anL-shaped bolt connecting said members for adjusting said support.

2. In an ensilage cutter, a flywheel, a knife support mounted on saidflywheel comprising a plurality of members, one of said members movablewith respect to the other member and having an encircling wall, andmeans extending through said wall for connecting said members foreffecting an adj ustment of said members. I

3. In an ensilage cutter, a flywheel, a knife support mounted on saidflywheel comprising a pair of oppositely disposed beveled members, andmeans extending through the beveled surfaces of said members forconnecting and. adjusting one of said members relative .to the othermember.

4:. In an ensilage cutter, a flywheel, a knife, a pair of adjustablebeveled surface members mounted on said flywheel for sup porting saidknife, a bolt extending through re eases said knife, and members forsecuring said knife to said flywheel, a second bolt extending throughsaid members for securing the same to said flywheel, and means extendingthrough the beveled surfaces of said members for effecting an adjustmentof said knife with respect to said flywheel.

5. In an ensilage cutter, a flywheel, a knife, a pair of adjustablemembers mounted on said flywheel for supporting said knife, a boltextending through said knife and members for securing said knife tosaidflywheel, a second bolt extending through said members for securing thesame to said flywheel and an L-shaped bolt disposed, between saidmembers for effecting an adjustment of said knife with respect to saidflywheel.

In testimony whereof I aflix my signature;

EDWARD s. CHARLES.
